Microscope Notes
The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power.
The amount of light transmitted to your eye is greatest at the low power. When you switch to a higher power, light (and therefore resolving power, or the ability to distinguish two nearby objects as separate) is reduced. Compensate with the light control (sometimes called the iris diaphragm

how does tempature impact air movement?
Answer:
The heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart.
Explanation:
Answer:
As you move higher off the ground, it gets colder *and vice versa*.
Explanation:
When we move off the ground, density is pulled down to the ground due to gravity. Therefore, it gets colder. It's also because of our atmosphere. (Vice versa, of course)
P.S. Density and gravity are also key parts of climate change, keep that in mind.

Give an example of a prokaryotic cell?
Answer:
blue-green algae
Explanation:
Answer:
Bacteria is the biggest example but these are also examples blue-green algae, E. coli, and mycoplasma.
Explanation:
This is what it is: Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

3. Callie has brown eyes, but her husband Joseph has blue eyes. All three of their children have
brown eyes. Do you know what Callie's genotype is? If yes, what is it? If no, why not?
Help please!!
Answer:
Since Callie has brown eyes, and all her children have brown eyes, we can only assume that the phenotype of brown eyes is dominand and Callie will have a dominant genotype, leaving Joseph to have a reccesive genotype (if Joseph was heterozygous for this aspect, he would have brown eyes) and the children will be heterozygous, with brown eyes as this characteristic predominates over blue eyes.

Which is endocrine function?
A. Pyloric glands release mucus to the stomach
B. Adrenal glands release adrenaline into the blood.
C. Esophageal glands release mucus into the esophagus
D. Salivary glands release saliva into the mouth
Answer:B. Adrenal glands release adrenaline into the blood.
Explanation:
The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions. With adrenal gland disorders, your glands make too much or not enough hormones
Adrenal glands are a type of endocrine glands that release hormones that include adrenaline into the blood. Thus, the correct option is B
Endocrine glands secrete their products directly in the surrounding interstitial fluid or blood, and not through ducts.
Adrenal glands are a pair of endocrine glands that are present superior to each kidney. It comprises of two distinct regions - adrenal cortex and adrenal medulla.
Adrenal cortex is the outer region of the adrenal gland that produces and secretes hormones like mineralocorticoids, glucocorticoids and androgens.
Adrenal medulla is the inner region of the adrenal gland and produces and secretes the hormones adrenaline and noradrenaline.

A. The deer population exceeded the carrying capacity, providing predators with a surplus of food. As the deer population
decreased, so did the carrying capacity.
B. The deer population increased as the carrying capacity stabilized. As the carrying capacity decreased, the deer population
decreased.
C. The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there
was less food available, reducing the carrying capacity.
D. As the deer population reached a maximum so did the carrying capacity. As the deer population decreased, so did the
carrying capacity until the environment stabilized and the deer population could increase again.
Answer:
C seems to be the most reasonable answer.
Explanation:
The graph depicts that in an ecosystem the deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

How would you describe the difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill?
The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.
At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.

what physiological (body) factors might cause one to get more squeezes, in other words, to have
Fatigue? (Hint: consider how the reactants of aerobic respiration get to your musde cells)
Answer: Heart strength and healthy circulatory system
Explanation:
Fatigue is considered to be the state in which a person cannot maintain the level of performance or training expected. Muscles are able to obtain energy by aerobic or anaerobic respiration and both use carbohydrates or sugars, but only aerobics needs oxygen. To perform physical activity, the heart pumps more oxygen to the muscles that are performing the exercise. When the muscles work harder, the body consumes more oxygen and produces more carbon dioxide. So, aerobic respiration is a type of metabolism in which the organism uses energy from organic molecules, especially as glucose, where the carbon is oxidized by the oxygen. 36 molecules of ATP per glucose are produced during aerobic respiration.
During an effort, the energy produced by aerobic breathing is not enough and muscles need to produce a complementary energy through anaerobic respiration which provides less energy than aerobic respiration. This type of cellular respiration produces waste products that the cells must eliminate, for example lactic acid, which remains in the muscles producing pain after exercise. Only 2 molecules of ATP are produced for each glucose during anaerobic respiration.
Therefore, the heart strength is important because that organ is responsible for carrying oxygen to the muscles, which is needed to perform cellular respiration and get more energy to perform the exercise. And there must be also a healthy circulatory system that delivers that oxygen to every part of the body.

The scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.
What is Cell theory?Cell theory was proposed by a German botanist M.J. Schleiden and a German zoologist T. Schwann. According to them, the cell theory states that:
All living organisms whether it is plant or animal is made up of cell.A cell is the smallest unit of all living organisms.The Cell is the structural and functional unit of organisms.Charles Darwin was popular in the field of evolution. Hence, he is referred to as the father of evolution. Robert Hook was known in order to discover a cell in 1665.
Later in 1855, the cell theory is further refined by German biologist R. Virchow. According to him, all cells are arising from pre-existing cells.
